    Thank you very much for great effort
    Kindly tell what Reference Reference sample has been taken..
    Is it ethanol???

    Another question: I have trichloroacetic acid solution already prepared 20%. Does it work as the 30% in this test or the concentration affects the analysis

    Great stuff. Thank you. Please can you share a video on p-Anisidine testing using the spectrophotometer.

    I have a question: in 5.50 you mix 5 ml of chloroform in the sample but in a plastic test tube.
    How is possible mix chloroform in a plastic tube ? Doesn't it "melt" ? Second question: is it possible about you to use dichloromethane instead of chloroform ? Its function is solvent, so dichloro should do the same.

    One more question: at 12.20 you do the blank. I don't understand, the blank is the empty clean cuvette or a cuvette with all the reagents without the oil ?

    This is great.
    Thank you so much.
    For the negative control, did you add all those reagents to it before you take the absorbance?
    Thanks

    Hello, I'm high school student from Korea. I want to conduct kries test to check rancidity of oils, but I need a literature explaining the method of kries test for citation.
    Can I ask if there is any material I can refer to?
    Your videos are so great and I really want to refer to it when doing experiment:)!!

      The reference of this video is ICMR-1990. The document of this reference can be found by searching on Google. Please collect it out. Thank you for referring me.

      @@MicroChemsExperiments Hello again:) Can I ask one more question? Our school does not provide UV spectrophotometer used in this video, but only have 'Go direct spectroVis Plus' spectrophotometer. Do you think I can set the wavelength at 545nm and only find out absorbance using this instrument? And what is the reason of fixing wavelength?

    Sir. Please mention the reference method for each. Rancidity. Acid value. Per oxide value. Because you mentioned reference all your previous apartments instead of this single one.

    • @MicroChemsExperiments
      @MicroChemsExperiments  3 ปีที่แล้ว

      We have already mentioned the reference test method of rancidity at the very begining of this video. So plz open this video again and find the reference method out.
      Similarly, open the video of peroxide value, Acid Value, FFA using the links given in the description section of thia video. Reference methods are also given for each of these tests at the very begining.
      Thank you.
